7-.l1hepresent invention relatesto new and useimprovements :in boats and :has for its 'pri- :mary object to provide, in ."a :manner as hereinafter set forth, a vessel which is capable of :great :speed -and which includes Inovel propelling '5 means.

Other objects :of the invention are to provide a boat of the character describedwhic'h will be simple in construction, strong, :durable, safe and which may be built and :operated -.'at low 'cost.

All of the foregoing :and :still further objects and advantages of the invention will become Capparent from a study :of the following specification, taken in connection with the accompanying drawings wherein .like :characters of reference designate corresponding parts throughout the :several. views, and wherein:

Figure 1 .is'a view in :side elevation of a boat constructed :in accordance with the present :invention.

.Figure 2is a viewin tion through the boat.

Figure 3 .is a "cross-sectional view, taken substantially on the line 33 of Figure -2.

Figure 4 is a fragmentary view in section, taken substantially on the line 4-4 of Figure 2.

Figure 5 is a cross-sectional view, taken substantially on the line 55 of Figure 1.

Figure 6 is a detail view in section, showing the mounting of one of the rotatably adjustable propeller blades on the hull.

Referring now' to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a hull vertical longitudinal secland .2 of the drawings,, the propeller blades 9 are arranged spirally on the hull I and also to define longitudinal rows. Fixed on theinner end ,portions of the stems II), of the propeller blades 9 are cross'he'ads- I'I. .Rods l2 connect the crossheads 'I-I of the blades '9 comprising the longitudinal rows for adjusting said blades inunison;

A support I3 is provided in the 111111 'I for the forward portion of the tubular shaft 5. Slidable 'on the tubular shaft 5 is a sleeve through the support I3. On the forwardend of the "sleeve I5 is a-flange 1 6. A hand lever Win the cabin 6 'is operatively connected to'the tubular sleeve I6 by a yoke I8 which is engaged with the huge I6. It will be "noted that the I constructionis such that the sleeve I5 may rotate I of suitable dimensions and material, said hull being in the form of a streamlined shell. Fixed in the forward end portion of the hull I is a centrally located longitudinal tubular shaft 2. The rear end portion of the shaft 2 is fixed in a suitable support 3 in the hull I. The forward end portion of the shaft 2 is mounted in the nose 4 of the hull I. Rotatably mounted in the rear or stem end portion of the hull I is a tubular shaft 5 which is aligned with the shaft 2. Mounted on the enclosure or cabin 6- the walls of which are The forward end of the cabin 6 is journaled on the shaft 2. At its rear end, the cabin 6 is fixed to the shaft 5.

shafts 2 and 5 is a pendulous A power plant I in the cabin 6 drives the shaft 2 through gears 8. hull I, to which the shaft In this manner the 2 is fixed, is rotated 6.

Rotatably mounted on the hull 'I are variable pitch propeller blades 9. As best seen in Figures ,5 around the members 20, 24, etc., for

changing the pitch of relative 'to the cabin 6 with the hull fl, Rods is connect the rear end "of the sleeve "I 5 :tozthe adjacent propeller blades 9.

:Extending through the tubular shaft 5 is a periscope 20. .Also extending through "the tubular shaft 5 and communicating with the cabin 16 is a ventilator 2L Mounted on the :stern "of the hull I is a rudder 22. cabin 6 actuates the rudder 22 through the medium of a rod 24, said rod being operable in the tubular shaft 5. A lining or bushing 25 is provided in the tubular shaft 5. A closure 26 on the forward end portion of the lining 25 closes and seals the forward end of the tubular shaft preventing Water from entering the cabin 6. Also extending through the tubular shaft 5 is a water discharge tube 21.

It is thought that the operation of the boatwill be readily apparent from a consideration of the foregoing. Briefly, the 'cabin 6 is suspended by gravity in a vertical position. As hereinbefore stated, the power plant 1 rotates the hull I through the gears 8, the shaft 2, etc. When the hull I is thus rotated said hull is caused to move forwardly through the water by the blades 9. By moving the sleeve I5 longitudinally on the tubular shaft 5 through the medium of the hand lever I I the pitch of the blades 9 may be adjusted as desired. Also, if desired, the sleeve I5 may be connected to a suitable governor driven by the power plant 1 thereby automatically the propeller blades 9. A door 28 is provided in the top of the cabin 6 to which access ishad through the medium of a ladder 29. The hull I is provided with a plurality of doors 30. g l

It is believed that the many advantages of a boat constructed in accordance with the present I5 which passes A hand lever 23 in the ably mounted to project on the exterior invention will be readily understood and although a preferred embodiment of said boat is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may beresorted to which Will fall within the'scope of the invention as claimed.

What is claimed is:

. 1. A boat of the character describedcomprising a rotary hull, a cabin mounted in said hull to remain stationary while the hull is rotated, motor means for rotating the hull relative to the cabin, a plurality of variable pitch propeller blades rotatably mounted to project on the exopposite ends of the" hull and journalled through the related partitions into the related ends of -the cabin, said cabin being rotatably mounted by the stub axles, and rotating means Within the cabin operatively connected with the front jstub axle for rotating the hull relative to the "cabin.

3. A boat of the character described comprising a rotary hollow hull, a cabin mounted within said hull to remain stationary'whilethe' hull is rotated, a power plant in said cabin operatively connected to the hull for rotating said hu11,-a plurality of variable pitch propeller blades rotatof' the hull, means connecting certain of the propeller blades for adjustment in unison, and operating means operable from within the cabin for adjusting the blades.

4. In a boat of the type comprising a rotatable hull, and a relatively stationary cabin mounted within the hull, a front stub axle fixed to the forward part of the hull and supportably journalled in a forward part of the cabin,v a rear stub axle fixed to a rearward part of the cabin and rotatably and supportably mounted in a rearward part of the hull, said stub axles thereby rotatably mounting the cabin in the hull, rotating means operatively connected to the front stub axle for rotating the hull relative to the cabin,

movement relative to the remainder of said second stub axle and to which said operating means is connected, said adjusting means further comprising means within the cabin for adjusting said slidable part.

5. In a boat of the type comprising a relatively stationary cabin and a rotatable hull enclosing the cabin, a front stub axle fixed to the forepart of the'hull and supportably journalled in, a forward part of the cabin, a rear stub axle comprising an inner element fixed to a rearward part of the cabin and supportably journalled in a rearward'part of the hull and a tubular slide telescoped on said inner element and arranged for axial movement'relative to said inner element, a plurality of adjustable pitch propeller blades projecting on the exterior of the hull, operating means within the hull for adjusting the pitch of the propeller blades in unison, and adjusting means located within the cabin and connected with said tubular slide for moving the slide to determine the pitch of the propeller KALMA FARKAS.
